T 0 all whomz't may concern.'

vBe it known that I, FRANK FLYNN, citizen of the United States, residingat Newark, in the county of Essex and State ofwNew Jersey, 'haveinvented certain new and useful Improvements Ain lMolds for ConcreteAStructures, of which the following is a specilication, reference beinghad to the accompanying drawings.

The present invention has for itsnpurpose the provision of a mold for#constructing concrete, cement or other plastic-structures of a hollowtype, preferably buildings, thecrete walls between the spaces, andwhich' intermediate walls connect with the exterior and-interior partsof the wall. Furthermore the auxiliary mold parts are capable of beingeasily removed, as the wall is constructed in a perpendicular direction,and adjustedy to a higher position.

A further purpose is the provision of timbers interconnected in'super-imposed positions on the exterior, to holdk theemold plates inplace, it being possible to remove the` lower timbers and raise them tohigher positions, until the wall is completed to the desired height.' iW A still further purpose is 'the provision .of means for supporting themold timbers on the upper edge of the concrete orl cement wall, as thewall is constructed.'

It is to be understood that the particulars herein given areinno waylimitative and that while still. keeping within the'scope of theinvention, any desired-modiications-of` detail and desired proportionsmaybe made in the apparatus according to circumstances.

The invention comprises further features and combination of parts, aswill be herein- `after set forth, shown in the drawings and claimed.

In the drawings: i

'f f e Figure 2 issan enlarged vdetailsectionalt plan view of a portion of the .walland the mold, showing thewedges or'spreaders `as having beenjwithdrawn from 'holding-'positions.whereby the interior moldplates for forming the air spaces may beremoved.

lReferring, to the drawings, 1 and 2" designate the interior andexterior mold plates, w

which may be any suitable pro-portions', ac-

cordingto the size .of wall or building to be constructed.l These platesare adapted to be arranged' in. parallelism, to forni the moldwalls, and3 and 4 denote the. mold platesbfor'forming. the air spaces'in theconcrete wall` 5.: Thesel plates 3 and L1sad.- )acent their vverticallongitudinal edgeson their inner surfaces have beveled ribsf.- In

beveled ribs 6, to force the plates 3 andlel These sections arelslightly tapered vertiv cally', as shown, in .fact the outer surface ofeach `section 'inclinestoward the inner sury face of each section at theupper endl -The lower end of each sectioniis provided with ariglitanglejcut away portion or recess 'which is of a shape 4oricontourto receive and engage the upper end of the adjacent section. \Vhere thesections of the timbers 11 interconnect in this manner, suitable boltsor screws 16 are employed, to hold the sections aligned. y

The upper sections 14 (which may act as the lower sections, when thesections 12 andv 13 are arranged above the section 14) have extendingtherethrough vrods or bolts 17, the nuts 1S of ywhich are adjustable onthe rods, to hold the timbers inplace, and to adjust themrelativelyspaced, for Lthe purpose of holding the mold plates. in position. As theconcrete wall increases in height, it is necessary to remove the lowersucceeding timbers,y and place them atthe top, and fur- G tliermore itis necessary to support the timbers on the wall. norderv to support thetimbers, props, such as rods 19, rest upon the upper edge of theunfinished wall, and are provided with forks 20, which straddle the`rods 17. Obviously the timbers may be held in position, as the wallincreases in height. As the wall is'constructed suitable tie or bindingrods 21 and 22 arearranged vertically and transversely in the outerportions of the wall of the structure, for the purpose of reinforcingt-he concrete or cement. Any form of reinforcing rods may be employed,tubular, solid orspiral rods may be embedded in the concrete or cement.Also embedded in the transverse connecting wall sections 23 aretransverselyI disposed reinforcing members 24. The inner portion of thewall of the structure, adjacent the corners thereof, and adjacent whe-rethe intermediate transverse wall parts are formed, vertical reinforcingrods 25 are used, which are connected to the horizontal and verticallreinforcing rods ofthe outer portion l ofthe wall, byineans of thetransverse'reinforcin'g rods 24. f

VVh'en the timbers'are placedl to hold the lexterior and interior moldvplates in position, theheadsV 18 .are adjusted uponv the rods v17, andthen the transverseI timbers 2G are disposed between the upper ends ofthe timbers 14,. in fact between the uppermost sections thereof, therebeing rods 27 or bolts passing through the ends of the upper sec tions,through the timbers 2G and have wing nuts or heads 28 to bind the partsinposition. It will be noted that by this construction the timbers 11may be held equally spaced.

Then the sections of the timbers 11 are arranged in position, the recessor cut away portion 15 of each section receives theupper end of theadjacent section, it being possible to remove the bolts or screws 1G ofthe lower sections, whereby the lower sections may be placed inengagement with the upper sections 14.- and vice `versa as the wallincreases in height. Suitable thumb screws 29 'are the sashes (notshown), and without usingl wood window frames. rEhe hollow spaces of thewall constitute means to receive the sash weights, hence it is possibleto form a wall structure having window openings, without the vnecessityof wood frames (not shown). Mold sections, similar to those previouslydescribed maybe used for forming the interior separating walls betweenthe rooms, and in sucha manner as to provide door openings, such asindicated at 83. Thesedoor openings 33 have their jambs provided withybolt-S34 embedded in the concrete, to hold.

.wood blockings 35, for the reception of the trimmings 36.,

. A building wall of this character serves to eliminate rats and miceand other pests, from inhabiting living houses, apartments and the like.Furthermore the air spaces formed within the walls will prevent thewalls from sweating on the interior. Furthermore the exterior of thewall may be stucco, but may be otherwise given a decorative effect, rasmay be desired,'the top of the building, or above the windows and door,or any other place. The use of window frames may be eliminated, the.walls may be made whatever thickness desired, it being possible yto usethe same structure of mold throughout the` entirewall structure. j

The exterior mold plates 2 may have different designs or impressionsurfaces, Aso that in constructing the wall, the exterior face of thewall may be decorated at the same time with the construction of thewall.

hold and support the door timber or frame- 36. The thumb screws 29 areswivelled in plates 29a (which bear against the' mold plates), and whenthe thumb screws are ro` tated or tightened, the plates bear against thelower mold plates `and hold them rin place, namely from slipping down.

The invention having been set forth, what is claimed as being useful'ist 1. In a mold for constructing building walls, Opposed mold boardsor plates spaced according to the'desired thickness of wall to be builtup, tapered timber sections disposed against the outer faces of saidplates and arranged vertically, the sections on each side being inalignment, the inner face of the lower end of each section being cutaway to receive and engage the upper end of an adjacent section, meansfor fastening the sections together where they connect, a rod connectingthe uppermost sections at a point above said plates and having abutmentmeans on its ends, and means between the extreme upper ends of the uppersections for spreading said upper ends and causing the lower ends of thelowermost sections tobind against the plates. i

2. In a mold for constructing building walls, opposed mold plates, to bespaced according to the thickness of wall to be constructed,interconnected timber sections arranged vertically adjacent theexteriorsurfaces of said plates, means passing through and connectingthe uppermost timber sec` tions at a point above the plates and providedwith abutment devices adjacent the ei:`

terior surfaces of the timber sections, spacing devices arranged betweenand connecting the extreme upper ends ot the timber sections, and holdthe timber sections spaced ac-` cording to the thickness of the wall,lsaid abutment devices being adjustable to draw the lower portions of thetimber sections adjacent to and in contact with said plates.

3. In a mold for constructing building walls, opposed mold plates, to bespaced according to the thickness of Wall to be con structed,interconnected timber sections ar ranged vertically adjacent theexterior surfaces of said plates, means'passingr through and connectingthe uppermost timber sections at 4a point above the plates and providedwith abutment devices adjacent the exterior surfaces of the timbersections, spacing devices arranged between and connecting the extremeupper ends of the tim.- ber sections, and hold the timber sectionsspaced according to the thickness of thewall, said abutment devicesbeing adjustable todraw the lower portions of the timber scc-A' tionsadjacent to and in contact with said plates, props engaging the means'which passes through and connects the timber sections to su ort thetimber sections in Josition, and means connectedto and carried by thelower ends of the timber sections for` i holding theplates in position.`y In testimony whereof I hereunto atx my signature.
